QUICK CONFIGURATION GUIDE
DT-504B
1 INTRODUCTION
The
DT-504B
is a module able to generate a single transport stream
in
COFDM
format from several audio / video (
A/V
) analogue signals.
It has 4 Audio / Video analogue inputs. Each
A/V
input has three
RCA
connectors, one for video signal (
VIDEO
) and two more for audio (right
and left audio).
Each
A/V
input is coded by means of the
MPEG-2
compression
system. Then the resulting signals are processed by a multiplexer that
brings together all in one
TS
. This TS is serialized into
DVB-ASI
format and
modulated in a
DVB-T
output signal.
Subsequently, the
DVB-T
output signal can be inserted into a
television network with the advantages of robustness and high quality that
digital technologies offers.

DT-504B
Configuration.
At the bottom, the screen shows the Transport Stream (
TS
) Status,
the
bitrate
used in kilobit per second and the percentage of bitrate used
relative to total available.
The
DT-504B
module adjusts the compression rate to the total
bitrate available, using the modulation parameters.
